chore: initial commit — portable agent memory & skill scaffold

Extracted and cleaned up from a prior WSL/Windows agent-memory setup.
Contains only project-agnostic content:

- Claude_Memory/: feedback rules, user profile, reusable reference docs,
  session scratch space (claude_info/, claude_log/), mirrored skill defs
- caveman/: ultra-compressed communication mode skill + subcommands
- html-slide-deck/: self-contained HTML slide deck builder skill

Project-specific knowledge (previously mixed in) was moved out to each
project's own repository as part of this cleanup.

+프로젝트 기획/스펙 문서(PROJECT.md, REQUIREMENTS.md, ROADMAP.md 류 — 특정 기획 도구 무관)는 caveman style로 작성.
+
+**Why:** 불필요한 설명 없이 핵심 정보만. 가독성·유지보수 효율.
+
+**How to apply:** 문장 대신 키워드/명사구 중심. 동사는 최소화. 설명 문단 지양.
